Comparative neuroprotective effects of antidiabetic medications on Parkinson's disease risk: A Bayesian network meta-analysis
Background: Diabetes mellitus is recognised as a risk factor for Parkinson's disease (PD); however, comparative evidence regarding PD risk across antidiabetic drug classes remains limited and inconsistent. We aimed to compare the risk of PD across different antidiabetic classes, with stratified analyses by age, sex, and cardiovascular disease (CVD) status. Methods: We searched the Cochrane Library, Embase, and PubMed until August 2025 for studies…
Prediction of dementia risk by instrumental activities of daily living limitations and its impact on dementia onset in combination with mild cognitive impairment: A population-based longitudinal study
This study validated the NCGG-ADL as an effective screening tool for assessing dementia risk among community-dwelling older adults. Furthermore, concomitant MCI and IADL limitations was associated with a higher risk of dementia onset more than either condition alone. Therefore, this coexisting condition should be carefully monitored to prevent dementia
Association between Covid-19 emergency declarations and physical activity among community-dwelling older adults enrolled in a physical activity measurement program: Evidence from a retrospective obser…
For the community-dwelling older adults who regularly self-monitor their physical activity, the current study concludes that there is no evidence of consistently negative impacts of the emergency declarations by the COVID-19 pandemic
Impact of Covid-19 Pandemic Exacerbation of Depressive Symptoms for Social Frailty from the Orange Registry
The increase in the rate of transition of elderly individuals to the social frailty group could have been related to the implementation of the stay-at-home order as part of the countermeasures for COVID-19. Furthermore, the increased prevalence of depressive symptoms associated with the stay-at-home order could also have influenced the increase in the prevalence of social frailty during the COVID-19 pandemic
Life Satisfaction and the Relationship between Mild Cognitive Impairment and Disability Incidence: An Observational Prospective Cohort Study
The relationship between the incidence of disability and cognitive function has been clarified, but whether life satisfaction is related to this relationship is unclear. Therefore, the purpose of this study was to clarify whether life satisfaction is related to the relationship between the incidence of disability and mild cognitive impairment. We included 2563 older adults from the National Center for Geriatrics and Gerontology-Study of Geriatric…
A New Life Satisfaction Scale Predicts Depressive Symptoms in a National Cohort of Older Japanese Adults
The 13-item questionnaire is a valid instrument for measuring the risk of depressive symptoms in older adults
A New Social Network Scale for Detecting Depressive Symptoms in Older Japanese Adults
Social engagement and networking deter depression among older adults. During the COVID-19 pandemic, older adults are especially at risk of isolation from face-to-face and non-face-to-face interactions. We developed the National Center for Geriatrics and Gerontology Social Network Scale (NCGG-SNS) to assess frequency of, and satisfaction with, social interactions. The NCGG-SNS consists of four domains: face-to-face/non-face-to-face interactions wi…
Predictive Validity of a New Instrumental Activities of Daily Living Scale for Detecting the Incidence of Functional Disability among Community-Dwelling Older Japanese Adults: A Prospective Cohort Stu…
We examined the predictive validity of a newly developed scale-the National Center for Geriatrics and Gerontology Activities of Daily Living (NCGG-ADL)-to measure instrumental activities of daily living (IADL) ability. We tested the scale for detecting new incidences of functional disability among community-dwelling older Japanese adults. Participants were 2708 older adults (mean age = 79.0 years, 51.6% women) living in the community who had no f…
Social Frailty Leads to the Development of Physical Frailty among Physically Non-Frail Adults: A Four-Year Follow-Up Longitudinal Cohort Study
Social frailty domains may play an important role in preventing physical decline and disability. The aim of this study is to examine the impact of social frailty as a risk factor for the future development of physical frailty among community-dwelling older adults who are not yet physically frail. A total of 1226 physically non-frail older adults were analyzed to provide a baseline. Participants completed a longitudinal assessment of their physica…
Effects of golf training on cognition in older adults: A randomised controlled trial
BACKGROUND: Although research indicates that a physically active lifestyle has the potential to prevent cognitive decline and dementia, the optimal type of physical activity/exercise remains unclear. The present study aimed to determine the cognitive benefits of a golf-training programme in community-dwelling older adults. METHODS: We conducted a randomised controlled trial between August 2016 and June 2017 at a general golf course. Participants …
Cognitive Functioning and Walking Speed in Older Adults as Predictors of Limitations in Self-Reported Instrumental Activity of Daily Living: Prospective Findings from the Obu Study of Health Promotion…
Our aim was to determine whether baseline measures of cognitive functioning, walking speed, and depressive status are independent predictors of limitations in instrumental activities of daily living (IADL) in older adults. The cross-sectional study involved 1329 community-dwelling adults, aged 75 years or older. At baseline, the Mini-Mental State Examination (MMSE), Symbol Digit Substitution Test (SDST), Geriatric Depressive Scale (GDS), and a wo…
The challenges of economic integration: The case of shipping in Asean countries
The Association of Southeast Asian Nations (ASEAN) has agreed to establish an ASEAN single-shipping market (ASSM) by 2015. This paper aims to assess the impediments in achieving this vision and how they can affect the pace of integration. These impediments include the differences in their national shipping capacity, national shipping policies and regulations, and in their quality of shipping-related infrastructure and institutions. Due to these d…
Reprints: Effects of an Intergenerational Health Promotion Program for Older Adults in Japan
We launched a new intervention study called REPRINTS in which senior volunteers engaged in reading picture books to children. Sixty-nine volunteers and 72 participants in a control group, all aged 60 years and over, living in three urban locations, participated in a baseline health checkup in June 2004. After completion of a three-month training seminar, volunteers visited public elementary schools and kindergartens in groups of 6 to 10 for an 18…
